To all whom it concern: p I Be it 'known that I, LUTHER-P. BRO N, a citizen of the United States, and a resident of Chicago, in the. county 10f Cook and State of 5 Illinois, have inventedcertain newand useful Im rovements in Box-Machines, of which the fo owing is a full, clear, and exact desc'ri tion.

' invention relates to paper box making 1 1 machines, and itsobject is to automatically l feed, paper box blanksto the machine, to paste the longitudinal edges thereof, to fold over and cement said pasted edges to complete the-box in its col aipsed condition, and to deliver and stacksai collapsed boxes in bundles containing -a given number ofthe same. This I accomplish by the means hereinaftetfully' described, and as particularly pointed out in the claims.

Referring to the drawings, A represents a suitable supporting frame for the machine embodying my invention.

' how lon as it forms a medium sem bling and enabling the It is immaterial for pro erly'asoperative. arts of the machine to perform their proper unc-' tions. 'Oneend of this frame 18 provided- 'with a send-circular trough-shaped dropa frame o'r which connects the horizontal plat 'formorbed of the main part of-the machine with the alining end portion of said bed,

this frame is'construc'ted or'supporteii so -tain the upper stretch of the apron in this horizontal position, I have provided the ma-v 7o chinewith longitudinal tracks C, which extend from thedrop frame a, tov which one end of the same. is secured, to the opposite end of the machine. 7 v

In order to ment'of the aprons B as they pass longitudinallyover'these tracks, I have provided the under surface of said aprons with a lon gitudinal cleat d of suitable flexible material, which is secured to and projects downwards so from the central portion of the belt and en ters a longitudinal groove e in said trackp substantially as shown in Fig. 8 of the drawingst v I I Y.

b are secured extends through its bearings and is provided-with a sprocket :wheel D, I which latter is'connected by asuitable chain D to 'thesprocket wheel D secured to the extended journal of latter has bearings upon the upper edge of the astereceptacle E located in thetrou 'h of t egframe a beneath the upper stretch of the apron B. p

The aprons B are designed not only to con- 95' vey the box-blankfrom the automatically. feeding-hopper, but are also designed to fold over the longitudinal side edges of the boxblank'as it moves throu h the machine, and cement the one edge of t edge. To accomplish this result, I provide the apron B midway its width'with a' con-" tinuous fly F, one side edge of which is se cured in a suitable'g roove or otherwise to the center of width of-the apron BL, This fly F 105 corres ends in width-to one-half the width of the agiro'n, and; -until after the apron is move past the trough-shaped drop-frame, the fly aps over the outer one-half of the apron B which is nearest the adjacent longi- 1'10 tudinal side of .themachine. J J m -,At a. suitable,po,i,nt on the track 0, after ceive the conveying aprons B, B, substan-eo prevent the lateral displace- One end of the shaft upon which pulleys paste-roller D which '90 p e same to the other loo v the belt has traveled past the trough-shaped drop-frame a, said track hassecured to=its side edge an L-shaped arm f, which is, preferably madeiof a flat strip of metal, with one of the branches thereof riveted or otherwise secured to the outer side edge of the track G,

- and with the other or horizontal branch tween the fly and the upper surface thereof,

thereof extending over the aprons B bethe inner half of the width of the apron B, B,

wooden blockcof suitable length which is. ar

farthest from. the adjacent longitudinal side of themachine. The former G comprises a ranged longitudinally over the half of the apron B, uncovered by the fly F, The base of this former G is but slightly above the up- ,per surface of the apron B, and its edge adj a- .-belt;, enters the angle made by the seamcent to the outer ongitudinal edge of'the which unites and secures the edge of the fly to the center of width of thebelt, the longitudinal side of this. former engaged by the fly,

" is inclined backwards or away from the same.

When the apron passes beyond the'arm, the

fly is given a semi-circular-turn, an the' apron is kept so taut that when once'the fly is given this turn it will continue to describe it at this point'while the machine is in operation. The blank when it reaches the former G passes under the same and as the fly makes its half-turn, the longitudinal edges of the blank are turned upwards and the angle of the bend made by turning it upwards is definedby' being brought in contact with the acute angle' or ed e of the former. When the longitudinal edges of the blank are thus folded over, the. dimension of the blank is such that the mar of one edge of the folded portion will a over the. margins of the opposite folded edge of the blank, and be cemented thereto 'b the paste which was supplied ,to the .un or side of said lap ing edges as it passes over the paste trou E. After leaving ti former G the. folds -colla sed boxes pass under and between a series;

'6) compression-rollers H, which cdmpletes the cementing of the lapping ed es of the box togetheri After leaving the ast' air of compression-rollers, and before the elivery rollem, 0 and c of the machine are reached, the fly is turned back to its original position ,again some to leave the folded collapsed box to be ,delivered straight out from and be-.

tween said rollers c, c.- This I accomplish by a vertically disposed guide-roller T which is journaled to a suitable stud depending from anarm t, which is shown in the drawings as projecting from the bearin s of-the last series of rollers H. This roller is located in such a plane that the fly will contact with it when in a vertical plane and will therebybepreupon vented from returning to the posltion which it assumed upon leaving. the former. The collapsedboxes are deliveredfrom rollers c and c to the lowermost of a series of boxes 71 which are constructed substantially as shown in Fig. 50f the drawings, and comprise a bottom, longitudinal sides and one end wall. The end of the box adjacent to the pulley c is omitted so that the collapsed boxes canbe pushed into and enter the same as they pass out of the machine, At about the center of length of these receiving-boxes I they are provided with suitable guide-plates g which have a vertical T-groove in them that engage a .vertical tenon on the inner side of the standard J, and along the side of the guidelates on one side of the boxes the latter are provided with a vertical rack h. is the collapsed boxes are fed to the receivmg boxes h, the latter moves downward by reason of the en agement of the rack h by the pinion and w 1en it passes out of engagement therewith, drops of its own weight a platform X, from which it can be re moved y the operator one at a time as desired. .ThepiniOn is secured on the end of a longitudinal spindle which is journaled in suitable hearings 1c at the base of the standard J which spindle is actuated through the medium of the sprocket and chain coimection I by the ion itudinal shaft K, which latter has a mitere connection with the lowermost of the last pair of compression-rollers,

H, substantially as shown in the drawings.

These gears and the rack and pinion are so timed and correlated that the lowermost box h is released andidrops to the latform X when say fift of the finished oxes have been delivers This forms a handy means for removing the finished boxes and at the same time furnish a reliable means for count-' ing and keeping score of the number turned out by the machine.

The pulley b at the receivin end of the machine has a superimposed pu ley L of less 5 width, engaging it, which is mounted on the shaft L that has bearings in blocks, that are depressed by coil-s rings m placed in the vertical slots" in the adjacent pendent end of the oose-necked portion of the superimposed ame,.M used in connection with the imachine. These pulleys L have their periphery slightly concaved and are connected ,by a rubber belt to similar ulleys journaled in suitable bearings located at points on the opposite side of the trough-shaped drop-frame a, and together with pulleys L form a conveyer for urging forward the box-blanks to the folding devices of the machine. This superimposed portion M of the machine consists of two corresponding inverted U-shaped frames, the strai ht portions of which are bent at right angles to) form supporting-feet therefor which are secdred to the to or bed of the machine.- Extending latera y from each side of the top of this U-shaped frame which is extended in a horizontal plane a dis-f tance about e nearly to the bedo of this horizontal portiont are suitable -t brackets 2 and 3, thelatter of qual, to the width of. the-U shaped sup ortmg-frame and-is turned, downwards to orm -a nose-neck,- that extends g the machine in the end of which is j Gtrrnaled the spring pressed roller L. At-suitable points on the u per level stretch here arise suitable standards or bearings in which are j ou'rnaled' sprocket wheels ,4 and 5 that are connected by a an endless chain 6.-; The latter sprocket desiteem of its. shaft si sprocket and chain from -an over head sourcesprocket'and, chain. extended t operate the series is connected by an endless 'machm upper Y ongitudinal rives motion from a pulley. mounted on its shaft that;is dri en by the belt 7, connected to a suitable ,driving mechanism.v On the opposite end ofth'e shaft carryin sprocket is driven, preferably, by a lower, and has. its journal opposite said rough its bearings and provided. with. an arm N. This arm N l a suchdimensions frointop to bottom as to holdthe'jbox-blank, and is referably shaped like a rhombohedron, wit its side nearest the pulley b of themachinefin clined away from the same. .The lower side 'edg'esiof the hopper. restand slideback and forth u on asurtable track secured to the edges of the siderails connecting the upperbends .of the le s of a 'tablefframeIP. .T ottom of the opper consists of a slattedendless belt p, or con- 'r-depressing arms moves the crossf ats' thereof catch a the transverse p it ram (10.
